Abstract
Quantum dot (QD) color conversion has recently been demonstrated in commercial QD‐OLED displays on the market exhibiting exceptional color gamut coverage, brightness, black levels, and viewing angles. To continue developing QDs for a wide range of future display technologies, two key aspects remain under study. First, how can blue light absorption be maximized for small pixel formats (<10 μm) requiring thin QD color conversion layers and second, as pixel sizes shrink and display brightness increases, how can these materials remain stable under high blue‐light excitation flux (up to 5W/cm 2)? Here we describe experiments addressing these two areas of continued development for heavy‐metal free QDs.
